So please give yourself a huge pat on the back, for surviving and progressing in the face of everything going on. Vladimir, same to you as well. And a special thank you actually to Vladimir here, who was one of our All-star Khan Academy Ambassadors. So he has an AP Bio, excuse me, AP Chemistry and AP Physics teacher, based in West Palm Beach, Florida. Even though he roots for the Miami Dolphins and I'm a Buffalo Bills fan, I am still getting Vladimir a mad love today, because he is taking time away from his own students to make sure that you have everything you need to serve yours. And so as you know, if you've joined previous webinars, you can ask Vladimir questions at any point, by typing into the questions feature of the GoToWebinar Control Panel and after we sort of talked through some of the basic stuff of Khan Academy, Vladimir we'll take your questions live, you'll actually be able to see on the site how he works his magic, how he gets the students engaged with chemistry and physics using Khan Academy. So just let's start there Vladimir, tell us a little about your background as an educator and then how you got started with Khan Academy. - This is my 21st year of teaching and I teach mostly AP Chem and AP Physics, but I also do Honors Chemistry and Honors Physics. And from time to time I teach mathematics too, which is kind of nice, I liked that too. I have been working with Khan Academy I guess from the beginning. And the reason why I started doing this is when I finished my doctorate degree, my doctorate degree is in Educational Technology and Instructional Design. So I kind of saw that this was where the future was going for us in education, I'll try to be concise. And so matter of fact, back in 2000, 2001, when I worked for Palm Beach County schools, we created a clearing house of materials free for all science teachers and we actually began training teachers in science and mathematics to use the tools that we have just given at the moment, which is very good. Back then it was just kinda the beginning stuff of using PowerPoint in the classroom and using some tools in order to enhance, the teaching of science and mathematics. It was an easy transition for us in science, because we had a lot of videos and a lot of different things that we could do, that will have a visual representation of what we do in science. Because sometimes it's incredibly complex to show for temple, let's say for example, a picture of an atom and people question, "How in the world do you see an atom? "How do we know that it exists that way?" But then we can show mathematical models and we can show 3D pictures, and for the students to grab a better understanding of very abstract components of science and mathematics that we see from time to time. So a biggest thing for a longer time. - Very cool and you're getting a little love here from April, who says Miami Dolphins rule. Whereas Janet says, she's a New York Giants fans so she has no judgment. Even though they tore our hearts apart in Super Bowl 25, but hey, that's ancient history now. Okay so that being said, let's cut to the chase here. I think folks right now are hurting in the sense that every educator in this country, every educator in this world frankly, is being forced to do things that they were not trained to do in most cases. When it comes to remote learning, using tools like this. If you were just getting started today, if you didn't have the advantage of a track record with Khan Academy, what would you do, if you were trying to serve your science students tomorrow or on Monday using a tool like Khan Academy? How would you start? - The way that I will begin is, obviously there's a wealth of information that we can find online. Especially when we need something that shows results and that is clearly delineated and that it is already broken down by subject, not only by subject but also by topic. And that it has resources, that also has a wonderful program with the community where you can ask questions, and there are a number of people who are involved and who can answer any of your questions. What I would do is, I would begin just showing my students just a basic understanding and creating a classroom in Khan Academy where my students can log on. Because it is a wonderful compliment to any classroom. I've been using it for a long time and I use it in my AP courses all the time. And is just being really a... It really is a game changer and the fact that we can deliver a location at any point and time, where we can create courses and we can create even assignment where the students can go at their own pace. You can integrate into any of your courses, because it perfectly aligns with whatever it is that you're looking for. To me it's the best resource that I've used. That's why I got really excited about it and I wanted to know more and I wanted to pass it on to other people. I have trained all of the science department in my school and the use of Khan Academy and everyone is already using it to assign to create courses, just to use that as a compliment for class, especially for AP courses. It's just unbelievable, it really is amazing. - Cool so, I've shared that community resource with everyone in the Chat. So if they want to talk to other Khan Academy Ambassadors, like Latimer, they can do that through that group. As far as talking to your students, it sounds like what you're saying is, you might actually do a Zoom meeting or Google Hangout meeting with your students now. And actually just pull this up on your screen and say, "Hey, here's Khan Academy, "here's what an exercise looks like." And that way they can see it, before you ask them to do anything, is that right? - Right, well yes I'm sorry, I kinda went a little further. I'm coming to thinking of myself and the way that I done it. But you're exactly correct and that is what I have pulled my teachers through, the teacher that I've trained to do it. The first thing you have to do is you have to go with your students very easy, maybe two or three days, where they can have a basic understanding of the navigation and all the things that are available in Khan Academy. But if you can set up a Google Hangout meet, actually I think it's called Google... They changed the name I believe. - Yeah, Google meet or whatever, yeah. - Or assume, for example, if you can use that and go step by step and showing your students how to sign up, how to find the resources, where the assignments are going to be located. But it's actually pretty intuitive to use. Once my teachers have used it for two or three times, they say, "Oh, I'm old." Some of my students would probably get it in one or two tries and then it becomes a wonderful resource. Once they begin using it more and more, the more proficient you become at it and the easier it is going to be to integrate into your own classes. - Very cool and so, maybe you show them an exercise, which you can always find just by searching at the very top. So just like I did, I went up to courses and I said, "Show me the AP Physics content or the AP Chemistry content." You can obviously search for anything in particular, so if you want to do Thermodynamics, knock yourself out, right? - Right, absolutely. - In terms of sort of getting students up to speed about the exercises, 'cause in some ways that's the heart of Khan Academy. How do you recommend that they tackle this? Do you say, "Hey, just go through it and do it once." Do you tell them to use hands or watch videos, how is your students think about this? - Well that's kind of interesting question, because I use it in a number of ways. And one way that I found very effective a couple of, maybe about a year ago or so is that again, now it's a little more complicated to do it because we're in a virtual environment. But I had tried it already and it actually works the same way that it will work in the classroom. And soon you can create small groups. Again, I haven't used a Google Meet too much, but I have done it in Zoom where for example, I assigned eight people that has already preloaded into my Google classroom assignments and my students will work to access that. And what I do is actually, I watched the video on Khan Academy first and I get the exact same question that they have used, and I used that question on just a Word document. What I do is I create the actual video link, as a QR code and once they begin answering the questions, then we all do a question first in different groups, and then we all come together again and we discuss the question and when I ask them to do after they have actually completed the question, then we click on the QR code, either do it on their phones or they do it straight on their computer. And then we can see how the question's actually done and then we talk about it and we compare the answers. And my students really, really liked that exercise because again it's a lot of confidence, once they say, "Oh really, I can do this, "or oh, this is what I went wrong. "Maybe I need to go back and review what I did "to make my corrections." So it works really, really well in that sense. - And just to give folks a sense of what's possible in addition to the videos, if you wanna actually look at some of those exercises together, you can come into your classroom. So let's say you've created a biology classroom or a chemistry classroom, you're coming to your assignment section and your score section, and you could actually look at those student answers as a class and say, "Hey, I noticed that half the class "got the wrong answer here, let's talk about that." So I bought the mistaken assumptions behind that and really tackle it as a class as opposed to you're on your own, good luck. (cross talking) That's a fair way of explaining, yeah. - Yes, absolutely 100% correct. Not only that, but I also like the fact that you can go into any of the assignments that you have given to your courses. And you can pick any individual student and you can see, for example, if I sign up one of my students, they say, "Oh Dr. V, I already know this question. "So what I'm going to do is, "I'm just going to watch the videos." I say, "Look, whatever you feel comfortable with, "I'm going to be okay with that, but what I want to see "is I want to see that you have actually watched the videos, "because that is how I am going to be sure "that you have actually watched them." And it gives me statistics on the time that they have watched the video. So if a student tells me, "Yeah, I've watch the video." And I said, "No, you actually only watched about 15 seconds "of the video, that doesn't equate." "Okay, I'll watch it." So it's a good way to also hold them accountable for what they say they are doing. So it's a wonderful resource, correct. - Absolutely, I'll just call out that. In addition to scoring the exercises, you can ask you to tell on your end whether students have read the articles and watch the videos by looking at their green check under those kinds of assignments. - Absolutely, and that could even be an assignment on its own right to, which I have done with my classes as well. I'd say once I see all the green check marks, then I know that you have completed all of your assignments you need to do, so you're going to get full credit for that assignment, if not then we have to go back and do it. And the good thing about it is like for the quizzes they... The other part that I like about is that they self adjust. They are going to go with what their student is answering and they have multiple times too. You can actually set it up that way to answer multiple times, instead of just one time, to give them a chance, so they can revise the question or review the question and then go back and answer it again. - Yeah, so do you think that like ultimately the goal of Khan Academy, is not just to be an assessment tool, but to be a mastery driving tool, where we encourage students to have those multiple temps and actually keep pushing themselves to really understand it at a deep level, not just the motions. - Absolutely, absolutely 100%. I agree with that statement a hundred percent on that, yes. - Cool, okay any other advice you wanna give teachers at this point or should we head into the questions from the audience? - I think we can take questions from the audience. I don't wanna take all the time explaining. I think, it would be better if we just answer what their needs are going to be at the moment, because I know that we have a number of people you say are going to be on there right now, or on there right now. - Yeah, we have about 230 science educators across the country, so no pressure Vladimir. But Sandy says, "Thank you for all that you do. "You are amazing, so thanks for making this possible." Similar love from April, even as a Dolphin'S fan. And let's talk through some of the questions that are coming in here. Okay so, okay, this is interesting. So you're gonna get a question that basically says, we've talked a lot about AP and like really making good progress and all that. If you have a special education student in your classroom, is there any way to differentiate using Khan Academy? Is there any way to make sure that every student is getting what they need not just sort of lock step for the entire class? - Absolutely, 100%. Because, Khan Academy is not only for... It's known to sign only for the higher level courses. It has every single level that you can imagine. It has from the basic levels all the way to a very high level AP and if you can access just any course that you want also by grade. Oh, it's on the screen right now. You can access by grade, but you can access it at any level. And the good thing about it too, again, is remember you can make it, so it's a self-phase guide that the students can follow and in their own time or in their own timeframe, whatever that needs to be at the moment right now, I think we're all in survival mode and we're all concentrating on more on the learning than in the actual assessment piece. But that's where we are right now. So it serves any student at any level, absolutely 100%, yes. - Cool and then just sort of build upon that, if you said, "Hey." I noticed that I have a student, no matter what their sort of situation is, who needs to go back and sort of fill in some gaps from over in the year, this could actually be a nice opportunity to do that. And you can actually make assignments of specific pieces of content, not just to your whole class but to individual students who really need that support. - Correct, absolutely. - Okay, so here's a related question from April. April wants to know, how you do your Pasic, Vladimir. Terms of all these videos, articles, quizzes. Are you willing them out, several at a time, one a day? What's your cadence? - It depends on the course again, because I teach from regular levels all the way to AP. In my regular level courses and honors courses, what I do is I do maybe two or three at a time, that they can watch. And depends also on the length of the video time, some of them are anywhere between seven and 60 minutes of play. So what are times only maybe one or two a day, because you have to be mindful to that, their home, it's a completely different situation right now and we want to follow our class, because we all believe that our classes are the most important classes, right? But we have to be mindful that they have other classes that they also have to meet with other teachers and not everyone is going to have the same level of comfort using the technology as of right now. And you probably are going through that right now experiencing the same, am I doing this correctly? And the answer is, yes you are because nobody really has a definite guideline on how this is going to be maybe a net in a month or so. And we'll probably will be in this situation for until the end of the year. So they said any way that you wish, but be mindful again, that they are going to be also having other classes and that might be a factor on how you space out are a little more. Again, I'm coming context. The first thing that I did, when I found out that I was going to be teaching online. I said, "Okay, let me see what is essential to me right now." So I went back into my curriculum and I said, "I can leave this out, I can leave this out, I can leave this out. Because the thing is that also the AP census a shortened version of what the content was going to be for the fan. And I had already finished covering everything so that was a good thing. For my other courses, I just went with the most necessary things that I need to do, so that they at least can continue to science. So you're gonna have to make that decision yourself depending on your experience and also depending on what it is that you want to cover throughout the year. - Great and one piece of advice I've heard from a lot of Ambassadors in these webinars, is just go slow at first. Don't try to like, come out of the barn racing 60 miles an hour, give yourself that time to build that foundation, the same we'd recommend for your students. - Correct. Another question, Katrina, there's actually a really appropriate for this screen, is are the lessons on Khan Academy aligned with the NGSS standards? - Yes. Yes they can be. They can be, but for the most part they do align. - Absolutely. - Absolutely 100%, and I know that because I actually went through the alignment process when I did my courses. I wanted to make sure that everything I was covering was actually quoted on that, but a hundred percent - Yeah, I'll give you a little sort of pro tip here. Not only does it have these sort of citations throughout the lessons, but you can actually search by standard. So if you knew the exact standard you needed, you'd come up here, you'd paste it in, and then voila, you've got the exact piece of content that's aligned with that too. - Right. - All right, great question. (cross talk) Ooh wow, okay, here is a really tough question for you. So Peter is saying, "I work with what are typically called "at-risk students, who are sometimes difficult "to engage in the classroom, let alone from a distance." With distance, every challenge is magnified and he's being really honest with us. He's like, I often use food as a hook, just the way to say, "Hey, come to my class and gauge. "What is the best way to draw my students, "giving that I no longer have that in-person relationship "to build upon. "How do I keep them motivated at a moment like this? - That is a really, really tough question to answer. Again, just because we're lacking that personal touch and that proximity and that connection that we did, there is no way that we can make the human connection through a computer. I know we try our best and I know that this is what we have been forced to do. Okay, this is no one's choice. But the way that I would say it is, it's just keep asking your students, keep the motivation, keep the faith. At the end of the day, at least in my 21 years of experience, I know that if I put my heart and soul into these things, my students are going to appreciate it and they are going to follow it. You have to show them that you love the subject, okay? And that you care about them and that you appreciate what they do. And your students are going to care about your class, once they know how much you care about them and about their future and about their... And I know and I'm probably sounding very idealistic and dreamy right now, but you know what that's just the way that I would approach it. I will put my heart into it and just say, "Look guys, we're gonna have to have do this. "Okay, this is just the way that it is going to do "and this is going to be important." Just to emphasize that this is going to be part of their future. That this is just the way that things are going to be right now. This is not always going to be the case, but just to keep going at it and to have faith and that's a difficult piece. Just to bring the motivation factor into it. Again, because we're not in the classroom and in my classroom, I'm very animated, I'm very high energy and that is the same projection that I try to bring to the screen, okay? I tried to make it that we have to do this for them and it is about them, number one. - Yeah I actually don't think that's idealistic at all. I think that's incredibly practical giving the world we're in. To like lose hope and to sort of throw up our hands as educators, is to ultimately drag us and the whole classroom down, we have to say strong. I will give a very practical piece of advice that I've heard from other ambassadors, is just keep the lines of communication open. And I know that it's doubly hard with at-risk students, because of maybe a lack of technological resources, but if you've access to texts or remind or ClassDojo or just whatever it is, if you can let them know that you're thinking about them and you care about them and you want to keep serving them. I think that reminds them that hey, they've got someone in their corner of the ring, and that's all every student craze right now. - Right. - Cool, okay amazing advice. Here's a really important question from Kathy, 'cause it speaks to the reality that a lot of teachers are going through right now. I know educators want to go online, they wanna do things like Zoom or Google Meetings or whatever, but a lot of districts are actually forbidding it in the name of equity saying, "Hey, until we can serve all of our students, "we just can't be doing live instruction." If Kathy is teaching in a district like that, what kind of advice would you give as far as how do you roll this out? Is even realistic to roll it out, if you can't do a live walkthrough, if all you could do is like, send an email or give a handout that said, "Hey, go to khanacademy.org and do this lesson, would that be enough? - I find that very difficult and it's kind of interest that you mentioned that because I actually had a phone call with a friend about a week ago, and his school district actually said, because of the inequality that we have, number one in technology and number two in just providing the resources that we need for the entire County. The County decided actually to shut down the schools, because if it's not going to be equitable for everyone then we cannot do it. And I guess they... In my understanding is that, that came from the legal team of the County. And in that sense, I really do not have an answer. Can you assign work that they can do on Khan Academy to continue? Absolutely 100%. Because I do that every year. I'll say, "Guys, if you want to go ahead, "this is what I will suggest." Because I have a lot of my students who are very interested in continuing and they say, "Hey, what do we do after AP? Maybe you could continue and do research or maybe you wanna look into it. Okay and maybe you want to continue and do your own self-paced course. But other than that, that is pretty tough question because most of the time, at least in my understanding that came from a legal team saying, "We cannot provide it because it's not going to be "equitable for everyone." And again, right now with the problem of the digital divide is a hundred times amplified. Even in my County, which is a pretty wealthy County in Florida, we're seeing the differences right now among the kids who have the technology and those who don't have it. Those who have maybe one computer at home and also need to share one computer among five, six brothers at home and their brothers and sisters. So it's a complicated topic. - Yeah, and I'll just give one very quick work around. If you're not able to walk them through registration and giving assignments and all that, one thing you can do to keep it really simple, is you can literally just send out the URLs for any piece of content on Khan Academy. - Yeah. - So for example, if you want people to watch this video about human body systems, we'll do this exercise about cells, you'll notice in a very top address bar, there's a unique URL that you could copy and paste into an email, into a text message, into a remind app. And that way, even if you can't walk them through the full experience, you can get your students working on something in the meantime. You're not gonna have tracking, you're not gonna have to look all the reports that we talked about, but at least it fills that void and get them learning in this sort of period of limbo. - Right. - Here is a really amazing and inspiring question from Sandy. So Sandy says, "Vladimir, I'm working with 160 "middle school students on a Pine Ridge Indian Reservation. "Talent is distributed evenly, but opportunity is not. "How can I help the students that are now remote, "to engage in more hands-on activities "with things they can easily find in their household." And for example, she teaches math, but she want it once to integrate with the whole steam spectrum. So makerspace, robotics, flight simulations, snap circuits, how can she bring that same hands-on learning sense of excitement and engagement, but do it virtually? - Well, that's a pretty interesting question because I am actually wondering myself, how am I going to do some of the basic things that I have done with my classes typically? But now that they're home and I don't know if they have the materials that they need to do it. And again, I cannot require them to go and buy anything right now, that would not be fair for them. I say, "Hey, go and find what you need." Because I don't wanna put anybody at risk of compacting anything, or be in contact with anyone who might be infected. But, that is a pretty tough question. Can I defer that one to you Jeremy? - Yeah, absolutely. I was gonna say that, I have been really inspired teaching my own kids, with the number of resources out there, way beyond Khan Academy. They have super simple like do yourself home experiment. So for example, this is super simple, it's for elementary school, but my daughter just dissolve the outside layer of an egg using vinegar. - Right. - This was like the most mind-blowing moment for them, even though it was just two things that I'm hopeful we all have in our house. I don't know about the eggs anymore giving the egg shortage, but at least the vinegar. And so hopefully that gives you a sense Sandy, that if you just check out what's out there on the Web, I guarantee you're gonna find lots of other nonprofits just like Khan Academy, that are in the STEM space that are offering resources like that. And I would encourage you to discover them and then also share them in the Khan Academy community, 'cause I know there are other educators who are in the same boat. - Right, and I guess I found that one a little hard to answer because again, I don't work with the little ones. And for example, for my students, I use a lot of simulations that are online that are wonderful, like the PhET Colorado. That is a wonderful resource that has tons of different demonstrations from physics, chemistry, biology. But again, it's a little more advanced geared towards the high school, college level type of students. - Great, okay so Elaine is gonna ask a really good advocate question. So we were talking before about this idea of doing multiple rounds on exercise. So you take a first version of the exercise, maybe you only score 50%, but you say, "I'm gonna push for mastery." So I do it again, this time I get 90% I'm in that mastery range. Elaine wants to know, how do you know they aren't just memorizing the answers to get a better score versus actually achieving mastery? - Well you know what, and we have wrestled with that question for a long, long time. Even before this, because I had that question many times before. And the other third question is going to be that as long as they've reached a mastery level and they are memorizing the questions, then I'm okay with that, because it is about exposure. At the end of the day, this is not the ultimate determination of their grade or the ultimate determination of the knowledge that they are going to have but I tell them too, "Guys, you need to go through this exercise, you need to do it in honest and you need to do it. Because at the end of the day, this might fall into intellectual suicide if you don't do it. You might be thinking, "Yes, I'm going to do it "because I'm going to copy the answer, "so I'm just going to ask my friend "what is the correct answer." But when it comes to answering the test, that's where you're going to prove to me that you either did it or you didn't do it. And a lot of times the students are going to be pretty receptive to that bonus but this is for your own benefit and this is the reason why we're doing this. So whether they do it and they go over again and say, "Oh, this is the answer to the question." At least they know what the correct answer to the question is going to be. So they are being exposed to what the correct answer and the correct procedure or whatever the question may be. So that's why we have to have just a little bit of, I would say trust in that they are doing it correctly. Now, is this going to be done with a 100% of the times? No, but most of them are actually going to do it in an honest way, in my experience at least. - Very cool and I will also mention that Khan Academy is not just showing the same four questions over and over again, for every single exercise it's drawing from a question bank. So yes, the student could memorize the answer and all 12 questions going through the multiple rounds, but you'll see that they did it seven or eight times, which will probably be a tip off of what's happening. So definitely take advantage of the breadth and depth of the content, as well as just that first iteration. That being said, I know we're almost at time here, so for the folks who didn't have their questions answered today, what other resources would you recommend for getting support? It sounded like the Khan Academy community was important. Anything else that you would turn to get advice or expertise from Khan? - The community is a great resource obviously that the website it's a great resource. And it's just a number of things that you actually can do, an introduction to new material that's the way that I've used it from time to time. I tell my students, if you guys are going to start for example, Thermodynamics and I want you to watch these two videos before you come to class, because I am going to begin with a discussion of why heat flows the way it flows. You can use it to compliment anything that you're having in your classes, again as resources. Remember the ability to integrate into any course too, it's just a wealth of information. As a matter of fact, you're gonna have to cut down on some of the information, because it was so extensive that it could be overwhelming if it's the first time that you see it, and maybe some of the things might not be appropriate for your classes. It is wonderful to use this for assignment, some assignment tool, a practice guide, getting ahead, you name it. Also the SAT Program that a lot of people know about. I have people who I have trained in Khan Academy and I said, "Wow, I didn't know that they had "an SAT program they can fall in." And actually I assign this to my students, as an assignment, I said, "You guys have to complete it once a week." You have to show up and I do a weekly assignment on SAT, and at the end of the year they're just thrilled about, "Wow, thank you for giving us that resource "because it was just a wonderful resource." But these are just some of the ways in which I have utilized and I'm sure that many other ambassadors and many other people have used it, they have many different ways of using it. But again, every time that I have a question that I do not know how to answer it, I immediately go to the community resources and I type the question and the number of answers I get, it's just wonderful. It's very helpful and people will answer your questions. It's just a great regrade resource. - Very cool, I think that's actually a perfect note to end on, which is not only is there this amazing community out there, but there are folks like Vladimir, who are sharing their own expertise and paying it forward to the next generation of Econ tutors. So Vladimir, thank you so much for doing exactly that for our entire audience of science educators say-- - Thank you for having me. - Thank you to everyone out there for investing time in today's session. I know it's been a long week, it's been a long month, I know there's a long road ahead, but we're getting there, we're taking one step at a time and the fact that you shared this time with us today, says a ton about your commitment to your students and serving them incredibly well. So thank you for all that you do. Thank you again Vladimir, and here's wishing everyone a peaceful and relaxing weekend. Thank you so much. - Jeremy, can I add one more thing before we go? Is there any way, because I know I have people who tell me, "Can you give us your contact information?" Is that even appropriate to say this is my email, if you have any questions you can email me and I will try my best to answer your questions or would that be something that is not... - Yeah, if you're comfortable, I'd be happy to share that in the follow-up email if that's okay. - Sure, that would be great. - Wonderful, well Vladimir again has just gone above and beyond, so if you have questions directly about AP Physics, AP Chemistry, or anything else, STEM related on Khan Academy.
